Its because you have a large pointcloud and PCL uses vtkLODActor(LOD = Level of detail), which on the lowest level is just a boundingbox.
https://vtk.org/doc/nightly/html/classvtkLODActor.html#details

In the docs they mention different things, that might make it possible not to due so. Ie. lower the required framerate. Try read up on it and if you find a solution, please post it here.
And maybe make a PR so it can be set/reset on an actor. Or specify what actor to use vtkActor vs vtkLODActor.
